API 5CT L80 Oilfield Casing And Tubing

API 5CT L80 Casing Tubing is a API 5CT Oil Casing Pipe & mainly used for oil well drilling. We manufacture API 5CT L80 Casing Tubing in accordance with the SY/T6194-96 standard, it is available as short thread type and long thread type supplied with their couplings.

According to American Petroleum Institute Standard API SPEC 5CT1988 1st edition, the steel grade of API 5CT oil casing pipe can be divided into ten types, including H-40, J-55, K-55, N-80, C-75, L-80, C-90, C-95, P-110 and Q-125. We supply the casing pipe & API 5CT L80 Casing Tubing accompanied with thread and coupling, or we offer our product in accordance with the following forms for option.

OCTG is shortened from Oil Countryside Tubular Goods, and that refer to your own special kind along with steel pipes, for the most part are seamless conduits but quite one particular proportion are welded ones, used intended for oil and flatulence exploitation and output. We can provide new customers with tubing, casing, drilling pipe and as well as others, which encompass the API bunch and the TP series, the later being of increased standard and by independent intellectual material goods rights.

API 5CT L80 Casing:

L80 Casing is placed downhole to provide structural integrity to the wellbore and must withstand external-collapse pressure from rock formations and internal-yield pressure from fluid and gas. It must also hold its own deadweight and withstand the torque and transaxial pressure placed on it while running downhole.

API 5CT L80 Tubing:

L80 Tubing is placed within the casing. It is used to transport oil and gas from the source rock to the wellhead.

    What are the differences between casing and tubing in general?

    • admin says:

      Tubings are usually run inside casing (cased hole) and serves as a conduit through which oil and gas is produced. It is basically a tube inside casing which is used to produce reservoir fluids.

    • admin says:

      Casing is generally a steel pipe installed in wellbore and is cemented in place to prevent Wellbore collapse, cross flow of fluids between different reservoirs and to control abnormal formation pressures.
